Virt-resize error (ntfs) : Fatal error: exception Guestfs.Error("ntfsresize_opts: /dev/vda2)
by Morgan Cox 21 Nov '11

Hi. Libguestfs 1.14 Ubuntu 11.10 I am trying use virt-resize on NTFS partitions. I have installed Windows 2008 in an LVM partition (in order to use RAW) - I am trying to resize to a larger LVM partition. I have ntfsresize installed on the server - the windows partition is not encrypted. root@kvm1:~# ntfsresize -v ntfsresize v2011.4.12AR.4 (libntfs-3g) The attempt ends with an error Fatal error: exception Guestfs.Error("ntfsresize_opts: /dev/vda2) I have attached a txt file of the results where I have used export LIBGUESTFS_DEBUG=1 ; export LIBGUESTFS_TRACE=1 I have also tried using virt-resize --expand /dev/sda2 /dev/vgpool/w2008webtemplate /dev/vgpool/wintest2 as well as virt-resize --expand /dev/vda2 /dev/vgpool/w2008webtemplate /dev/vgpool/wintest2 Any ideas how to get it working ?

Possible issue with virt-v2v writing to wrong Windows registry control set
by Greg Scott 18 Nov '11

18 Nov '11

I may have stumbled across a virt-v2v bug. I just did a successful virt-v2v migration of a Windows 2008 server from an ESXi host to a RHEV environment. While the VM was still on the ESXi side, I removed its VMWare tools and rebooted it just make sure it was still functional. Then I shut it down and V2V'd and imported it into RHEV. When I first powered up the new RHEV copy, it found and installed the driver for the Virtio NIC and tried to install the Viostor SCSI driver, but failed with "Access Denied". This was strange. Looking at the Windows Device Manager, I noticed a SCSI controller without any driver and an "Unknown Device". This looked similar to the situation when it was an ESXi VM. I tinkered around with drivers a little bit, trying to be the Viostor stuff to load. It never did. So I rebooted the VM, just to make sure it would come back up while I was there to watch it and I could deal with its missing 2nd disk drive later. Good call - it went into a crash/reboot loop. Bummer. I caught it and tried "Last Known Good" from the Windows boot menu. This never works, but I keep trying anyway. Good thing, because this time it came right back up. It also successfully loaded the Viostor block driver this time and now there are no more SCSI controllers without drivers and no more Unidentified Devices. And that VM's second hard drive also showed up - this was probably the "unknown device" from before. I wonder if virt-v2v wrote its registry updates to the wrong registry control set and I stumbled across it? And a tip for anyone else - if your Windows VM crashes after a virt-v2v, try booting with Last Known Good. - Greg Scott

[ANNOUNCE] libguestfs webinar TOMORROW (Friday)
by Richard W.M. Jones 18 Nov '11

18 Nov '11

I'll be holding a libguestfs live “webinar” tomorrow, Friday, 18th November 2011 at 16:00 UTC. To convert the date and time to your timezone, do: date -d '2011-11-17 16:00Z' The programme will include: - An introduction to libguestfs features. - Live demonstrations of guestfish, a Python program, inspection, and image resizing. - An overview of major new features in RHEL 6.3. - The opportunity to ask questions on any technical topic related to libguestfs. This is going to be a Webex conference. It's possible, albeit difficult, to get Webex working on Linux. You will need the Java plugin for your browser, and there are some other tips on my blog: https://rwmj.wordpress.com/2011/11/17/libguestfs-web-seminar-this-friday/ The Webex conference link, an accompanying handout, and other details will be posted to the above URL ^^ shortly before the session starts. Don't worry if you can't make it or can't get Webex to work, as it will all be recorded and placed online in an open format as soon as we can afterwards. This seminar is sponsored by Red Hat.

I don't see this error myself. I just unpacked febootstrap-3.12 from the tarball, and ./configure && make works fine.

I'm fairly sure you don't need autoconf and automake, to build from the tarball. Building from git does of course require these. OCaml and ocaml-findlib are already mentioned in the README file.
